Surface Temperature Generated in Oscillating Contact

微动疲劳和微动腐蚀是由振动接触引起的摩擦学损伤的常见类型。将研究在这些条件下接触区摩擦产生的表面温度水平及其对微动过程的影响。通过红外显微镜获得的实验温度测量将与摩擦学微动数据和相关的传热学分析相结合，建立温度在微动损伤中的作用模型。滑动距离和速度以及氧化膜的影响将被包括在内。这项研究将有助于更好地了解微动过程，并可能为微动条件下的材料选择和开发提供更好的指导方针。

Fretting fatigue and fretting corrosion are common types of tribological damage caused by oscillating contacts. The level of surface temperature generated by friction in the contact zone under these conditions and its effect on the fretting process will be studied. Experimental temperature measurements obtained by infrared microscopy will be combined with tribological fretting data and with relevant heat transfer analyses to formulate a model for the role of temperature in fretting damage. Effects of sliding distance and velocity as well as of oxide films will be included. The study will result in a better understanding of the fretting process and could lead to better guidelines for materials selection and development for fretting conditions.
